The invention discloses a reductive dehalogenation method of an organic halide. In the inert gas atmosphere, the organic halide shown as the formula I or the formula II is subjected to reductive dehalogenation to generate an organic compound shown as the formula III or the formula IV (the formulas are shown as the description) in the presence of a catalyst, alkali and a solvent, wherein the reaction temperature is controlled to 90-100 DEG C. The reductive dehalogenation method has the advantages that the range of substrates is widened; the solvent in use does not need extra phosphorous ligands, the price is relatively cheap, and the consumption can be greatly reduced to 0.1 mol%; the solvent in use serves as a hydrogen source and reacts, the operation is simple, a lot reactions can reach quantitative yields, and when the reactions are scaled up to gram level reactions, almost quantitative yields can still be achieved.
